Master the Science of Sourdough. Keep Baking Knowledge Free for Everyone.

The Sourdough Framework is more than a book. It is your definitive guide to baking with intuition, confidence, and consistency. Every hardcover purchased is a direct contribution to my mission of providing open-source baking education to home bakers around the world.

From Frustration to Freedom: Your Journey to Confident Baking

Are you tired of following recipes to the letter, only to pull dense, disappointing loaves from your oven? Do you feel like you're just guessing, hoping that this time it will finally work?

My name is Hendrik, and as an engineer and obsessive home baker, I shared that frustration. I knew there had to be a logical system behind great bread, a set of principles that, once understood, would lead to consistent success.

That's why I created The Sourdough Framework.

This is not another collection of rigid recipes. It is a complete system designed to teach you the why behind the how. It's a visual, first-principles approach that will empower you to:

Understand the Science, Simply: Finally grasp how time, temperature, and hydration truly work together. No more guesswork.

Bake with Unshakable Confidence: Learn to read your dough and make adjustments on the fly, adapting to your unique kitchen environment.

Troubleshoot Like a Pro: Armed with detailed flowcharts and a complete visual toolkit, you’ll know exactly how to diagnose and fix any issue, from a sluggish starter to an overproofed loaf.

Adapt Any Recipe, or Create Your Own: Break free from dependency. Use the framework's principles to modify existing recipes or develop your own signature breads with predictable, brilliant results.

My commitment is to make this knowledge accessible to everyone. That is why the entire text of this framework is, and always will be, available for free online.

This premium hardcover edition is for those who want a permanent, beautifully crafted tool for their kitchen and wish to partner with me in this mission. It is made possible by a community of supporters, including over 1,100 original Kickstarter backers, who believe that baking knowledge belongs to the world.

Built for the Baker, Not the Browser

A Distraction-Free Sanctuary: Leave the phone, tablet, and endless browser tabs behind. Immerse yourself in the craft of baking with a focused, tactile experience that a screen can never replicate.

Engineered for the Countertop: With its durable, smyth-sewn, lay-flat binding, the book stays open to the page you need, even with flour on your hands. No more propping, no more losing your place.

Your Personal Baking Journal: I printed this book on high-quality, uncoated paper with generous margins, inviting you to make it your own. Scribble notes, record your timings, and document your discoveries. Over time, it will become more than a guide, it will be the living record of your sourdough journey.

A Beautiful, Gift-Worthy Object: This is a tool designed to be used, but also an object crafted to be admired. It’s the perfect gift for the aspiring or experienced baker in your life who appreciates quality, design, and the pursuit of mastery.

Selected customer reviews

Ulrich Roxburgh  - Best Sourdough Guide I've ever seen: "Seriously, I've been making bread for 25 years, and sourdough for at least 5, but II still picked up heaps of useful hints, and inspiration to try out new things as well. This has seriously raised my game when making Sourdough. My family are all very impressed."

Joanne Helm - Amazing and very informative: "New to sourdough baking, and looking for guidance, you helped me beyond my expectations! Your step-by-step explanation of the process was the difference between success and failure! Thank you, my sourdough was a success!

Eric Wiltz - I couldn't be more pleased with my purchase: "I have yet to read the entire book but to date, I couldn't be happier. At the age of 67, I'm a new baker and the Bread Code will make you an, "educated sour dough baker!" I'll be trying the wet starter today on simple bread and I'm anxiously awaiting the flavors it produces. I also purchased the starter, at day three of reactivation, it's produced a much sweeter aroma than the starter I started with. You can't go wrong with this wonderful sour dough reference bible!"

About the Author

Frustrated by inconsistent recipes, software engineer Hendrik Kleinwächter applied his passion for logic to deconstruct sourdough. He created this framework to empower home bakers with the scientific understanding needed to bake with confidence and predictability.
